Summary: Deliberate changes: * save snapshots to s3 prior to migrations. * label migration snapshots in s3 metadata. * avoid pruning migration snapshots for a month. Opportunistic changes: * Associate document timezone with snapshots, so pruning can respect timezones. * Associate actionHash/Num with snapshots. * Record time of last change in snapshots (rather than just s3 upload time, which could be a while later). This ended up being a biggish change, because there was nowhere ideal to put tags (list of possibilities in diff).
